Patent JP-S6416640-A (JP)
Title: Manufacture of laminated steel sheet
Inventor: YOKOYA HIROICHI
IPC: B32B15/08
Filed: 1987-07-10
Abstract: PURPOSE:To form a laminated steel sheet, having no defect such as pin holes or the like on a metallic foil, by a method wherein the width W1 of a resin film is made smaller than the width W2 of a steel belt and the width W3 of a metallic foil and the steel belt and the metallic foil are short-circuited at the outside of the width W1 of the resin film. CONSTITUTION:The width W2 of a steel belt 2 and the width W3 of a metallic foil 14 are in the relation of W1<W2<W3 with respect to the width W1 of a resin film 13 and the metallic foil 14 is short-circuited with the steel belt 2 at the outside of the width W1 of the resin film. According to such a short-circuit, the potential difference between the metallic foil 14 and the steel belt 2 is near to the value of 0MV without limit in the whole area of a conveying passage from the bonding part of the metallic foil and the steel belt to a delivery side conductor roll. Accordingly, when conducted current (or conducted voltage) is large, or the thickness of the resin film is thin and the threshold potential of dielectric breakdown is low, pin holes will never be generated on the metallic foil 14 due to spark discharge through the resin film 13.

Title: Single valve incylinder injection 4-cycle engine
Inventor: TSUKAMOTO TOKIHIRO
IPC: F02B75/02
Filed: 1983-09-19
Abstract: PURPOSE:To shorten the initial burning time and to reduce noise by forming the surface of heat-resistant filter such as ceramic filter arranged in suction tube into scale or step. CONSTITUTION:A single valve incylinder 4-cycle engine is not provided with a throttle valve but provided with single valve 5 for performing suction/exhaust. A heat-resistant filter 12 such as a ceramic filter is arranged in the suction tube 9 to form the surface of filter 12 into scale or step. Upon heating of said filter 12 by exhaust gas, intake air will counter flow through a port into the cylinder and heated. Consequently, the initial burning time is shortened to reduce noise. While the particles produced in exhaust stroke can be adhered to the surface of filter then blown into the cylinder in suction stroke and burnt again to purify the exhaust gas.

Title: Air intake system for engine
Inventor: TOKUSHIGE HIROYUKI
IPC: F02D41/12
Filed: 1990-06-27
Abstract: PURPOSE:To improve the combustibility of a gas mixture after the ending of decelerated operation by closing throttle valves arranged in respective branched intake passages, and controlling a throttle valve arranged in a collecting intake passage to be opened, when a car is operated under the condition of deceleration. CONSTITUTION:When a car is decelerated, throttle valves 5a-5f of respective branched intake passages are controlled to be closed, and for the first stage of decelerated operation from the start of the decelerated operation up to the elapsed time of a timer T, a throttle valve 9 of a collecting intake passage 8a is controlled to be opened. Thus, an intake negative pressure is generated only in the intake passage parts on the downstream side of the valves 5a-5f, and the upstream side of the valves to which air is introduced by the opened state of the throttle valve 9 of the collecting intake passage 8a, is at atmospheric pressure. In this case, since the volume of the passages on the downstream side of the valves 5a-5f is small, the intake negative pressure becomes small, and even when the period for which an intake valve and an exhaust valve are overlapped, is set to be wide, the quantity of dilution gas after combustion to be introduced to the respective branched intake passages is restricted to be decreased.

Abstract: PURPOSE:To generate a large damping force by installing a movable wall onto which a piston is attached, at the stroke final edge part in a cylinder and allowing working-oil to flow-away through the movable wall or an orifice set between the movable wall and the cylinder wall. CONSTITUTION:When a piston rod 5 is pushed to the final edge, the caulk edge part 5a of the piston rod 5 collides with the head part of a guide bolt 23, and pushed into with a movable wall 25, and the oil in a working-oil chamber 26 is pressurized, and resistance is increased, and the oil flows into a pressurizing chamber 1 through an orifice 28 formed between the movable wall 25 and a cylinder 1. Since the passage area of the orifice 28 is small, a large damping force is generated. During transfer to a reverse cycle, the movable wall 25 shiftes, pressed by a spring 30, and the capacity of the working-oil chamber 26 increases, and a relief valve 29 is bent by the reduction of the pressure in the working-oil chamber 26, and a relief hole 27 is opened to introduce the working-oil into the working-oil chamber 26, and thus the movable wall 25 is restored.
